Make a Ring by Melting Pennies.

!!!Caution!!! Melting pennies will release Zinc Oxide fumes which cause flu-like symptoms including fever, chills, nausea, headache, fatigue, muscle aches, joint pains, shortness of breath, chest pain, and cough. Use a well ventilated area with power assisted ventilation to avoid breathing these fumes.



That being said, this is ring made from pennies. You can smelt the copper coating off leaving you with zinc. Pennies minted after 1983 are all made like this.



You don’t have to have a lathe to do this. You could always hammer the ingot flat and follow the nickel ring instructions. A surprising thing is how lite it is. My wedding ring is the same size weighing 8 grams. This ring weighs in at 3.

smelt 1 (sm lt). v. smelt·ed, smelt·ing, smelts. v.tr. To melt or fuse (ores) in order to separate the metallic constituents.

I placed 10 pennies on a spoon and heated them with a propane torch. The spoon was held with locking pliers, which was held by a wooded clamp. Once the zinc liquefied I removed the copper with a metal probe (I used a light tester I had near by).

I then poured it into a section of ½” pipe and let it cool off.

Here I machined the ends off the blank then drilled a hole through it. I chucked the same drill bit into the lathe. Next I wedged the blank on by placing a plastic bag over the bit. Finally the outside was machined.

To expand the blank I hammered it over a pry bar. I started out with a small bar then moved up sizes as the ring expanded. To get to my ring size I eventually had to hammer over a ½ socket bit.

Of course to get your size simply stop hammering once it fits.

I evened out the ring with a file. I then spun it on a ½” socket bit and sanded it with 1000 grit then 200 grit sandpaper.

Lastly I buffed it on a buffing wheel.

Thanks for reading.
